| Low Permittivity | Big force (Force is greatest when charges are in a vacuum) |
| Formula for permittivity | ε = εᵣ ε₀ |
| Size of force between collinear charges | The same on each body |
| Direction of force between collinear charges | Along the line joining the two charges; It is an attractive force if the charges are unlike, and repulsive if they are like charges |
